Factual error: The girl is killed by having paint all over her body, supposedly suffocating her. While a widely believed theory at the time, it is not actually true that you can be suffocated by cutting off air to the skin - as long as you are still breathing, you won't suffocate. The only way damage might be caused is that by being unable to sweat/cool, you might get heatstroke, alternatively the toxic elements of the paint might prove fatal, but both of those effects would take far longer to kill you.

Deliberate mistake: Goldfinger has imprisoned Bond in a jail cell guarded by an Asian. Bond draws the Asian into the cell by smiling through the small barred prison door window and then slowly sinking out of sight. When the Asian enters the cell, Bond drops on him from above. While it is physically possible for Bond to work his way up the walls into that position, he could not do it in the time elapsed nor could he do it without passing his body in front of the small barred window (which would be seen by the Asian guard).
Revealing mistake: At the beginning of the film, Bond shoots his rope gun to climb over the wall. If you look closely, the rope he shot didn't even come out of his gun. It comes from off the left side of the screen. Very visible in slo-mo, or paused
Continuity mistake: In the teaser, when Bond has come out of the water and climbed up the cliff, right after he kicks the guard he is seen running away. In that frame you can see he is wearing leather shoes with light brown leather soles - which are completely dry. He was not wearing those in the water.
Factual error: Due to the actual weight of gold, it would be inconceviabe for the gold to be stacked in such a way as it is depicted in Fort Knox.
Revealing mistake: When Bond is at the hotel at Miami, in several scenes you can see that film was shot at a hotel, and then the editors placed the card game opponent's figure in the film. The filming of the figures is a lot clearer and crisper, while the background looks like a homemade film.
Continuity mistake: After we first see Tilly Masterson's car overtaking Bond's Aston, the next few shots of the scenery are inconsistent. What is seen through Bond's car windows does not match the scenery in the subsequent long shots. And Tilly's car is shown leaving the village, then after getting out on the open road, the shot through her rear window shows her leaving the village again.
Other mistake: After Goldfinger has lost the golf round and is about to depart, Bond hands Oddjob the Slazenger 7 and says 'I believe this is yours'. Oddjob (who's obviously upset that Goldfinger lost) crushes the golf ball and throws it out the window. It's ridiculous. 1: Golf balls have a liquid or rubber core, so you'd see the residue. 2: A golf ball has several very hard layers to prevent it from collapsing on a hard impact. 3: When Oddjob throws it, look closely and it looks a bit like a section of a styrofoam cup.
Continuity mistake: When Oddjob drives into the junkyard, watch his shadow as he exits the car. Then look at the shadows while he drives off. Some hours have passed between the shootings, perhaps the missing hours are the ones it took for the engine to be removed from the car? (Check the other mistake from this scene).
Audio problem: When Bond fights Oddjob in Fort Knox, he tries to hit Oddjob with a metal pole, but it ends up to wall, and Oddjob cuts it with his hand. The remaining piece of pole falls to floor and it sounds like the pole is made of styrox.
